' To all whom it may concern: Be it knownjthat I, GEORGE 0. Cinema,

- citizen of the United States, resident of East 1 Orange, in the county of Essex and State. of New Jersey, have made a certain new and useful'lnvention in Re 'sters; and I declare the following to be a clear, and exact description of the same, such as will'enable others skilled inthe art to whiichit appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of; reference marked thereon, which form specification V Figure 1 is a vertical section of a portion of a register embodying the invention.

The invention has relation to the. frame structure and key-stem structureof adding machines and registers having a series of depressible denominational keys, an object being to facilitate the assembly of the key stems in the machine; Another object is to provide a machine wherein more room is iafiorded for the working parts; these working parts are'more'accessible for examina- .tion,' lubrication and repair, and the machine .is capable of more economical-manufacture. Other objects and advantages; will hereinafter appear. 7

The invention consists in the novel coirstruction and combinations of parts, as liereiliafter set forth.

In the accompanying drawings, illustrat ing theinventionas applied to the mach ne ofmy Zco-pe'nding application Serial No. 202,533, the numeral 2 designates the sup porting' frame, made up partly of a plurahty of vertical frame plates 3, each extending parallel to a denominational-senes 1 of keys, and having a top plate A provided, with a series of slots or perforations 5, en-

madeup of' planular or fiat-metal and dis posed at right-angles to the planes of the plates 3, and said slots of form correspondi to the cross-section of said stems. ach frame, plate 3 relating to a denominational series of keys is provided with lower substantially vertical slots 10, in so ries, each key stem 6 having a lower extension or lug 11 laterally enga ing and sliding mits respective slot 10- an provided with lower end of the retracting upper end of said spring suitably connected:

The' lateral lug 11 of each key stem is usually in the plane of the stem and has a' downward and lateral extension or ofisetportion 15, one edge of which works adjacent to a lateral face of the adjacent plate 3. The

extension 15 is usually bent arcuately from the plates 3 are open, so that the key stems may be engaged therewith or let down therein from above, after said stems are engaged, with the perforations of thetop plate, and means are provided to olosethe open upper v ends of the slots, preferab'ly consisting of ends at 17 to the respective frame plates and having upper forwardly extending ends 18,

located over the laterally extending lower parts 11 'of the keystems, said ends 18 later ally offset at 1 9 over the tops of the slots 10 and abutting' against one edge of the out away-portion .10 i'n-the plate 3, to limit the pivotal movement of the latch. s' Thelatches 16 will in this way limit the upward movement of the keys. Lateral movement of each key stemin'one laterally \ofiset upper end 19 ofthe latch, 100

an outer perforation 12, engaged by the spring 13, the t direction will be limited by engagement of,

the key stem being thereby, at is lower portion, guided in a true path in its endwise or longitudinal movement. v

" The latches .16, being pivoted as stated,

are releasable to 0 en'the upper ends ,of'the slots '10, so that t e key stems may beinserted in the machine in the assembly thereof, and withdrawn upwardly and out of the machine when required. Each latch is provided with a tail lever end 20, extendin usually rearwardly from its pivot an adapted for the application of pressure in engaging the offset upper ends of the latch over and closing the upper ends of the slots, and reversely in releasing the latches, as stated. When the latches are in normal position, closing the upper ends of the slots, these tail lever ends 20, have their lower edges located in the same plane as the lower edges of the vertical frame plates 3, "and when the. assembled machine is placed in its outer casing, these tail ends engage the top surface of the horizontal base 21, of said casing, being thereb held or locked in position. The lower e ges of the plates 3 rest. upon the top surface of the baseQl and take the weight of the machine.

The latches are conveniently moved from released position, with their tail ends extending downwardly below the lower edges of the plates 3, pivotally to normal position, bypressing the otherwise assembled machine upon a horizontal or flat base.

To accomplish the release of is necessary to first lift-the machine from the base latches wi no longer be gagement aforesaid. These latcheshave a in the locking enfrictional bind upon an their pivots, so that they do not work easily,

whereby, in assembling the machine, and prior to the association of the assembled machine with the outer inclosing and rotecting casin 2, and the base 21 thereof, the

latches will e heldsecurely against acci-- dental or casual pivotal movement, which would eflect the release of the parts of the machine held imposition thereby as .previouslystateds 1 a an I claim:
